RADIATOR FOR AUTOMOBILES.

Specification of Letters Patent.

Application filed February 17, 1905. Serial No. 246,110.

To all whom it may concern.-

Be it known that I, JOSEPH B. LONG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Radiators for Automobiles, of which the following is a. specification.

The type of radiator most extensively used consists of what is commonlyl called a coil of tubing having extended radiatingsurfaces. The so-called coil" consists of a number of straight sections of tubing suitable means at a distance of about onefourth of an inch apart. In another type of radiator the extended radiating-surface consists of a continuous flange disposed spirally around the tube and provided with radial crimps or corrugations. The diameter of the tube varies, as does also the area of the extended radiating-surface and the distance apart of the disk flanges and the convolutions of the spiral flange. With these details the present invention has'nothing to do. On the contrary, it is applicable to tubular radiators generally, and 1n the present application I have shown it in connection with a tubular radiator'having a spiral flange.-

Tubular radiators of the types mentioned are desirable because they afford for the water an ample passage which is not liable to sto page by foreign substances 1n the water or by the de osit of scale on the interior of the tubes. It is found, however, that the flanges, which are usually made of copper of about one thirty-second of an inch in thickness, are fra'il and bend out of shape by very slight pressure. There is a type of radiator Whichconsists of a great number of flat tubes which are crimped or corrugated transversely, so that whenassembled the radiator presents a cellular appearance resembling somewhat a-V honeycom This-l appearance is preferred by many to the appearance resented by the tubular radiator having anges of any of the forms above mentioned.

One object of the present invention is to provide a tubular radiator having extended radiating-surfaces in the form of flanges which presents either at the front or at the back or at both the front and back the appearance of the so-called cellular or honeycomb radiator.

Another object of the invention is to provide means for strenfrthening and protecting the flanges of a tubular radiator.

Still another object of the invention is to provide a tubular radiator with the additional radiating-surfaces.

These objects are accomplished by the constructions which are hereinafter described with reference to the accompanying drawing, which is made a part of this specification, and in which- Figure 1 is a front elevation of a radiator embodying the invention. Fig. 2 is an elevation, full size, of a fragment of the cellular facing shown in Fig. 1. Fig. 3 is a horizontal section, on a somewhat reduced scale, of one end of a radiator.

The straight parallel branches A of the coil pass through plates B and have their extremities connected in series by means of .bends C, so as to form a single complete cirstated, a cellular facing H, the constructionV of which is shown in detail in Fig. 2, is arranged on the front and rear sides of the radiator or upon one side only, as may be desired. This facing is constructed of the aforesaid corrugated strips, so arranged that their summits contact with each other, the whole being secured together by soldering or galvanizing, or by any other suitable means. This cellular facing contacts with the outer peripheries of the flanges and not only protects them from injury but in addition thereto provides extended radiating-surfaces and presents the cellular or. honeycomb appearance already described. Y

I have in the foregoing description referred to the facing as being cellular or having the ap earance of honeycomb; but I desire to have 1t understood that any foraminous or reticulated structure used as a facing for concealing and protecting the delicate Patented Feb. 19, 1997.

flanges Which provide the extended radiating-surfaces is within the scope of the invention.

What I claim as new, and desire to secure 5 by Letters'Patent, isl 1. Ina device of the classdescribed; a coil having extended radiating-surfaces, and corrugated stri s arranged with their summits vopposite an in contact with each other, said 1o strips being arranged in contact with the extended radiat-ing-suri'aces, Whereby they rovide additional extended radiating-suraces and whereby they protect theradatingsurfaces rst aforesaid, substantially as de- 2. Ina device of the class described, a'coil` having ianges providin extended radiating; surfaces, and oorrugate strips arranged with their summits opposite and contacting with each other, said strips being also arranged in contact With said flanges, at the front of the radiator, whereby they provide additional extended radiating-surfaces. and at thev same time protect said flanges, substantially as described.
